Machine vision for locating objects
Hasík, Dávid ; Huzlík, Rostislav (referee) ; Vetiška, Jan (advisor)
The bachelor’s thesis deals with design of machine vision system for object localization and its application possibilities. Design approach, its components and their individual advantages and disadvantages for this type of machine vision system are described. This thesis also includes simple model of machine vision system for object localization using regular PC. For image processing is used Vision Assistant and its tools. Two scripts are made in this software and their performance is compared.

Evaluation of targets in shooting range based on image data
Sujová, Sára ; Šťastný, Jiří (referee) ; Škrabánek, Pavel (advisor)
The thesis describes the design and implementation of a computer vision system for evaluating targets on the shooting range using image data. The program respects the restrictions based on safety measures established by the the shooting range manager and uses an uniform system of lighting and camera placement. The work consists of several parts. The first part is the creation of the dataset and its annotation. The second part is the creation of the program. The program includes a photo of the target, which is suitably edited and divided into sub-areas in the pre-processing phase. These sub-regions are then iteratively processed by the U-NET network, which produces segmentation maps that are subsequently combined into the resulting map. The positions of the detected shots are obtained from this map. In the last part of the program, a point evaluation of the shooting session is obtained.

Using machine vision for robot guidance
Gábik, Jaroslav ; Štěpánek, Vojtěch (referee) ; Vetiška, Jan (advisor)
With the development of machine vision technologies, new applications that can increase production, versatility or simplicity of production systems are widely spread. This thesis deals with usage of machine vision for robot guidance. The task consists of creating a technique and its practical realization, where the proposed assumptions are verified. The main objective is to determine 3D position and orientation of a sheet metal part or subassembly of the body-in-white, which is lying within the reach of an industrial robot with respect to its base coordinate system. The proposed method is suitable for several types and dimensions of components, which meet certain requirements. Targeting the component is carried out by scanning significant points on the component with the help of the 3D scanner attached to the robot flange. Afterwards, gained data are processed in a designed programme. The theoretical part is focused on research in the field of machine vision, accuracy of industrial robots, compensation of their errors and manipulation and assembly of the sheet metal parts in automotive. Finally, an evaluation and recommendations for practice are provided.

Bin picking of non-oriented components using a parallel manipulator
Novák, David ; Marada, Tomáš (referee) ; Štěpánek, Vojtěch (advisor)
This master's thesis deals with the design of sorting unoriented components using a parallel manipulator. In the literature review section, it describes machine vision methods and important aspects when selecting a suitable camera for machine vision, which will be used for robot navigation. This section also discusses robot programming methods and describes possible approaches to programming robot movement. The practical part includes the design of the fourth axis of a delta manipulator in the NX Siemens environment, which allows for the orientation of manipulated objects. The software section presents the design of PLC control in the TwinCAT3 program. In this environment, functionalities for inverse kinematics, trajectory planning, image processing, and HMI for robot operation are utilized. Furthermore, a functional model was created in the virtual NX MCD environment, which communicated with TwinCAT3 via an OPC server.
